This page covers biological details of component group Sensory Thalamus. Component group is part of aHuman target integrated biological model.

• Top-down path to center: Forebrain Diencephalon -> Thalamus (FD.TH) -> Sensory Thalamus (FD.TH.SR) (see Mind Maps)
• Function: Relay primary or secondary assending sensory streams

Components

Component items:

• Lateral Geniculate Nucleus (NSA.FD.LGN): Temporal decorrelation
• Medial Geniculate Body (NSA.FD.TH.MGB): Detection of the relative intensity and duration of a sound, relay to Auditory Cortex
• Ventral Posterior Nuclei (NSA.FD.TH.VP)
  • Ventral Posteroinferior Nucleus (NSA.FD.TH.VPI): Relays pain and temperature from body to insula
  • Ventral Posterolateral Nucleus (NSA.FD.TH.VPL): Relays somatic information from body to S1
  • Ventral Posteromedial Nucleus (NSA.FD.TH.VPM): Relays somatic information from face to S1
• Pulvinar (FD.PV)
  • Inferior Pulvinar (NSA.FD.TH.IPV): Dorsal =Where= Stream
  • Lateral Pulvinar (NSA.FD.TH.LPV): Ventral =What= Stream
  • Medial Pulvinar (NPE.FD.TH.MPV): Integration of associative cortical information and projects to visuomotor-related cortex
  • Oral Pulvinar (NPE.FD.TH.OPV): Somatosensory functions
• Posterior Thalamus (FD.TH.PTH)
  • Limitans Nucleus of Thalamus (FEC.FD.TH.LI): Multisensory projection to striatum
  • Suprageniculate Nucleus of Thalamus (NSA.FD.TH.SG): Spatial coding of auditory information
  • Submedial Nucleus of Thalamus (NDM.FD.TH.SM): Pain center
